(Read Revelation 15:5-8)

In the judgments God executes upon antichrist and his followers, he fulfils the prophecies and promises of his word. These angels are prepared for their work, clothed with pure and white linen, their breasts girded with golden girdles, representing the holiness, and righteousness, and excellence of these dealings with men. They are ministers of Divine justice, and do every thing in a pure and holy manner. They were armed with the wrath of God against his enemies. Even the meanest creature, when armed with the anger of God, will be too hard for any man in the world. The angels received the vials from one of the four living creatures, one of the ministers of the true church, as in answer to the prayers of the ministers and people of God. Antichrist could not be destroyed without a great shock to all the world, and even the people of God would be in trouble and confusion while the great work was doing. The greatest deliverances of the church are brought about by awful and astonishing steps of Providence; and the happy state of the true church will not begin till obstinate enemies shall be destroyed, and lukewarm or formal Christians are purified. Then, whatever is against Scripture being purged away, the whole church shall be spiritual, and the whole being brought to purity, unity, and spirituality, shall be firmly established.
